Tourbillon Regulator AK04
The implicit utility of the AKRIVIA signature tourbillon is shown explicitly for the first time in the Tourbillon Regulator AK04. A blued seconds hand is mounted above the one-minute tourbillon cage, minutes are indicated via a central hand and hours via a separate counter at the twelve o’clock position. Just as the AK02 is the time-only variation of the AK01 movement, the AK04 is the time-only variation of the AK03 movement.
Historical regulator timepieces were deliberately built without complexity, because their entire mechanism and power reserve were solely for the purpose of precision timekeeping. They had separate axes for all indications in order to promote readability. These are the elements now expressed in the Tourbillon Regulator AK04 by AKRIVIA.
Precision is emphasised in the Tourbillon Regulateur
